摘要
应用有限元法计算分析了330kV输电线路复合绝缘子干燥洁净状态下的电位和电场分布,讨论了杆塔和导线对绝缘子串的电位和电场分布的影响。计算结果表明,绝缘子串中靠近导线侧和高压侧10%的部分电场畸变严重,高压导线的存在使绝缘子电位分布相对均匀。杆塔对高压侧场强影响更显著,“有杆塔和导线”时高压侧最大场强相对“有杆塔无导线”时高压侧最大场强降低了60%左右。
Calculation and evaluation of the electric field and potential distribution was performed in the design and development of composite insulators for 330 kV transmission lines. The effects of tower and conductor on the electric field and potential distribution along the insulators were investigated. Simulating calculation result shows severe field distortion at conductor and earthing top at 10 percent height of insulator adjacent to line and HV end. The conductor improves the electric potential distribution along the insulators. More apparent effect has the tower on field distribution on HV side, which was lowered by 60% in the case of the tower being equipped with conductor versus that without conductor.
